6. After installing new belts, make sure they
are tensioned properly.
Work Lamp Bulb
The Work Lamp uses a standard medium-base
60 watt bulb.
Band Saw Operation
Consult “Features and Terminology” on page 7
for identification of the controls.
Unlock the control panel using the provided
keys.
Never operate the band saw
without blade covers in place and secured.
Blade Break-In Procedure
New blades are very sharp and, therefore, have
a tooth geometry that is easily damaged if a
careful break-in procedure is not followed.
Consult the blade manufacturer’s literature for
break-in of specific blades on specific materials.
The following procedure will be adequate,
however, for break-in of JET-supplied blades on
lower alloy ferrous materials.
1. Use a section of round stock.
2. Operate the saw at low speed. Start the cut
with a very light feed rate.
3. When the saw has completed about 1/3 of
the cut, increase the feed rate slightly and
allow the saw to complete the cut.
4. Keep the feed rate at the same setting and
begin a second cut on the same or similar
workpiece.
5. When the saw has completed about 1/3 of
the cut, increase the feed rate while
watching the chip formation until cutting is at
its most efficient rate (refer to “Evaluating
Cutting Efficiency” below). Allow the saw to
complete the cut.
6. The blade is now considered ready for use.
Setting Blade Speed
1. Refer to the Speed and Pitch selection chart
on page 23. Select the speed setting for the
material to be cut.
2. While the machine is NOT running, move
the gear shift lever to the required speed
setting (high or low). See Figure 14.
Move the gear shift lever
only when the machine is NOT running, to
prevent damage to the gearbox. Figure 14
